100

X-rays are a form of this type of radiation.

electromagnetic radiation

100

Harmful effect of x-rays that damages cell

ionization

100

Dark areas on a radiograph are called this

radiolucent

100

Film becomes this after processing

radiograph

100

Bitewing shows this part of teeth.

crowns and part of roots

200

X-rays travel at this speed

the speed of light

200

Time between exposure and visible effects

latent period

200

White/light areas are called this

radiopaque

200

First step in processing.

development

200

Used to detect interproximal decay.

bitewing

300

Shorter wavelengths result in this

greater energy and penetration

300

Radiation damage that builds over time.

cumulative effect

300

Overall darkness of an image

density

300

Second step in processing

rinsing

300

Shows entire tooth and apex.

periapical

400

The process that occurs when the filament is heated

thermionic emission

400

Large dose in a short time

acute exposure

400

Difference between black, white, and gray shades

contrast

400

Third step in processing.

fixation

400

Used for root and bone pathology

periapical radiograph

500

Where electrons originate in the x-ray tube

cathode

500

Small doses over long time

chronic exposure

500

Controlled by mAs

density

500

Final step in processing

drying

500

Too steep vertical angulation causes this.

foreshortening
